I try to set up postfix as a mailserver for incoming mails for mydomain.
I have the following questions:
- where can i set up a user-db or which one is used?
- how can i handle a virtual maps table for mapping E-Mail-adresses to users or mailboxes?
- where can i define the forwarding e.g. to dovecot on another Server? can i use lmtp?
Thanks,
Roger

Hi,
the postfix plugin acts only as a relay, so there won't be any local users, mailboxes or lmtp.
-
Hi,
This means, just as a relay for outgoing mail, not for incoming in that case?
Are there plans to Change this (e.g. db-plugin, ldap...)

Sure, also for incoming, but you have to use smtp in the transport table ..
-
i see, this means this here:
- Add a relayhost-entry to main.cf on the internal lan mailserver for outgoing mails to other Domains via opnsense
- Add mydomain.org smtp:mailserver.mydomain.org in the transport-file on the opnsense postfix and add the line transport_maps = hash:/usr/local/etc/postfix/transport in main.cf
I'll try that. Thx!

The relay host is only for outgoing mails. If you have a dynamic IP and a public server which relays for you then this is the host to set. If you have a static IP and a PTR you can use the firewall itself to relay to the world.
In Domains you set your internal domains and as host the internal mailserver.
That's all :)
